Answer: heres the 3 main functions.
Explanation:
membranes have three primary functions 1) they keep toxic substances out of the cell 2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment and 3) they separate vital but incompatible metabolic processes conducted within organelles.
All the above is correct.
Answer:
Metaphase
Explanation:
In prophase, spindle fibers start emerging from the centrosomes. In metaphase, the spindle fibers attach to the sister chromatids.
A male and female, sperm and egg.
The graph shows that the rate of photosynthesis increases with increased light intensity, other conditions being constant.
<h3>Photosynthesis and light intensity</h3>
From the graph, the rate of photosynthesis increases with an increase in light intensity.
At low light intensity, the photosynthesis rate increases with an increase in the concentration of carbon dioxide and level off at some point.
With medium light intensity, the rate of photosynthesis is about twice that of low light intensity under the same concentration of carbon dioxide. It also gradually levels off when the concentration of carbon dioxide reached a particular point.
The same trend applies to high light intensity. The rate of photosynthesis increased accordingly, much more than low and medium-intensity light.
Both light and carbon dioxide concentration can limit the rate of photosynthesis. When both factors are abundant, photosynthesis can be limited by other factors such as water, nutrient, etc.
